Area forecast discussion, May 2, 8:03 PM CDT, 6 hours 11 minutes before
SOUTHEAST TEXAS AND SOUTHWEST LOUISIANA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAKE CHARLES LA 803 PM CDT TUE MAY 2 2000 RAINFALL SHOULD RETURN TO THE LCH FORECAST AREA AFTER MIDNIGHT BUT BEFORE DAWN. WILL MAKE COSMETIC CHANGES TO CURRENT FORECAST PACKAGE TO INCLUDE AREAS OF FOG AND TIMING OF SHOWERS/THUNDERSTORMS. WILL NOT ADJUST TEMPS/POPS. 09 AFTERNOON DISCUSSION... ...A RAIN EVENT EXPECTED THROUGH WEDNESDAY... .FIRST PERIOD... SCATTERED CONVECTIVE RAINS ARE EXPECTED TO RETURN SHORTLY AFTER MIDNIGHT...BECOMING MORE NUMEROUS NEAR DAWN. WITHIN THE LOWER TROPOSPHERE...THE SYNOPTIC FEATURES ARE CONFIGURED FOR GENTLE LIFT. DEEP SOUTHERLIES ARE ADVECTING GULF AIR NORTH...WHICH SUBSEQUENTLY SLIDES ACROSS A FILM OF RAIN-COOLED AIR NEAR THE GROUND. THE ETA GUIDANCE FURTHER REINFORCES THIS IDEA OF GENTLE LIFT...BY DEPICTING ISENTROPIC LIFT ON THE 300 DEG K ISENTROPE (ROUGHLY REPRESENTS THE SUBCLOUD LAYER). WITHIN THE UPPER TROPOSPHERE...THE SYNOPTIC FEATURES ARE CONFIGURED FOR ABRUPT LIFT. THE RIGHT REAR QUADRANT OF A SOUTHWESTERLY JET STREAK WILL FOCUS QUASI-GEOSTROPHIC LIFT OVER THE FORECAST AREA (FA) NEAR DAWN. WITH THIS IN MIND...I EXPECT SCATTERED TSTMS TO SUBSEQUENTLY ORGANIZE INTO LINES...MAKING FOR A ROUGH EARLY MORNING COMMUTE. I WILL RE-ISSUE THE SPS (SPECIAL WEATHER STATEMENT) TO STRESS THE RAINY MORNING COMMUTE. .SECOND PERIOD... THE PRIMARY RAIN-MAKER...THE QUASI-STATIONARY CUT-OFF LOW WILL WOBBLE EAST ALONG THE EASTERN TEXAS-OKLAHOMA BORDER. THIS SLOWLY-FILLING LOW WILL CONTINUE EJECTING VORTLOBE SPOKES (SHORT-WAVES) ACROSS THE FA. MOISTURE FLUX CONVERGENCE WITHIN A DEEP LAYER WILL CONTINUE SUPPLYING THE FA WITH HIGH PRECIPITABLE WATER (PW) VALUES. WITH PW VALUES RUNNING NEAR 140 PERCENT OF NORMAL...BASIN-AVERAGE RAINFALL AMOUNTS NEAR 2 INCHES WITH LOCALIZED 4 INCHES ARE POSSIBLE. I EXPECT MOST OF THE HEAVY RAINS TO CONCENTRATE NEAR A PW RIDGE (AXIS EXTENDS FROM JACKSON THROUGH LAKE CHARLES). AT THIS TIME...I BELIEVE THAT FFS (URBAN AND SMALL STREAM ADVISORY) WILL HANDLE THE RAIN EVENT. .THIRD PERIOD... CONVECTIVE RAINS EXPECTED TO PERSIST...AS WOBBLING CUT-OFF LOW CONTINUES EJECTING VORTLOBE SPOKES ACROSS THE FA. .COASTAL WATERS... MEAN SEA-LEVEL PRES GRADIENT DOES NOT SUPPORT ADVISORY WINDS. THE MARINE FORECASTER WILL DROP THE SMALL CRAFT ADVISORY OVER THE COASTAL WATERS. HOWEVER...TSTMS...SOME ORGANIZING IN LINES...WILL BE A PROBLEM. 21-TRARES .LCH... LA...NONE. TX...NONE. PRELIM NUMBERS... LCH 67/77/67/80 5545 LFT 65/80/65/81 4545 AEX 65/80/65/81 4545 BPT 67/78/67/82 5545
